I prefer much cleaner design. Take a look at these guys:http://www.malwarebytes.org/
Also I don't like animations of any kind. And since you guys are a "cleaner" software company your design should also signify cleanliness and simplicity. Just my $0.02.

Blue and white is a good combination as it's associated with trust and purity. These are qualities that you want to portray. However, extensive use of light blue and white encourages boredom. You don't want your site to look pale and uninteresting to the eyes of a new site visitor.

Suggestions:

a) Since blue is our main brand color, add in some dark blue (preferably the reflective/glossy type) to complement the present combination. Example: MBAM

b) Aside from blue, red is another dominant color for businesses. In Privazer's case, red was used sparingly (which is good) but why not...

Create a tab for the links at the top of the page ("Home Download Support Company Press") and use Red as the color. Example: ZDNet

c) There are a few shades of grey/silver used on the site. Leave the ones at the center of the page. Replace the lighter grey areas on the side with black as it adds sophistication. By using black at the sides, you are also encouraging users to focus on the contents within the center of the page
(rather than get distracted by the empty spaces)

I can't help but to notice that there are similarities to what I've suggested earlier on. If you don't mind creating another mockup, I have a few suggestions:

a) The position of grey and black on the sides currently looks rather disjointed. 2 options:

i. Inverse the 2 colors and lower the line (where they split) to the same level as "Secure cleanup, In-depth cleanup, Privacy Protection".
ii. Do away with it altogether and opt for entire black.

b) Maybe I'm mistaken but the screenshot makes the center of the page looks narrow. I think it needs to be slightly wider. We want the sides (and black/grey color) to complement...not steal the space. Blue is still the main brand color. Something along the lines of 20:60:20 ratio (approx)?
